Wallpaper - Under The Sea

Our Under The Sea wallpaper brings an illustrated ocean world to life with a gentle, hand-painted watercolour character. Set against a calm steel blue background, the design features a playful mix of marine creatures, including striped angelfish, soft pink jellyfish, spotted stingrays, blowfish, and tiny silver fish drifting between delicate bubbles. The balance between larger focal creatures and smaller floating elements creates a rhythmic, open repeat across the wall. As with all Wallism wallpapers, this design is made-to-measure to your exact wall dimensions and printed on PVC-free paper with a subtle surface structure.

In the room

We love this design for spaces dedicated to young children, including nurseries, toddler rooms, kids' bedrooms, and playrooms. Because the steel blue background provides a grounding, cohesive base, the wallpaper works beautifully across multiple walls without feeling visually overwhelming. On a single feature wall behind a cot, toddler bed, or low storage unit, the individual sea creatures stand out clearly, offering plenty of gentle detail to catch the eye. The motif also translates wonderfully into a family bathroom, where the oceanic theme feels right at home while maintaining a soft, sophisticated backdrop.

Styling it

When styling a room around our Under The Sea mural wallpapers, we recommend pairing the design with light, natural materials that complement its gentle watercolour tones.

• Choose furniture in pale blonde woods like birch, light ash, or clean white finishes to keep the room bright and open.
• Introduce soft textiles in muted coral, blush, or warm cream to pick up on the friendly tones of the fish and jellyfish.
• Keep wall shelving and decorative accents simple and uncluttered so the illustrated underwater scene remains the primary focal point of the space.

Colour combinations

The backdrop of our wallpaper is a soothing steel blue, accented by soft coral pinks, warm peach, crisp white, charcoal black stripes, and touches of silvery grey. To create a balanced interior, we suggest pairing it with surrounding walls or woodwork in soft off-whites, warm greys, or muted blush tones. If you want a more enveloping, immersive look, matching the trim and adjacent walls to a tonal slate or steel blue will create a seamless and cosy atmosphere.
